1. Both VAM buckle and Hunting buckle are special buckle types used in oil casing and other fields
2. Series and type
VAM buckle: Belongs to the VAM series, with multiple derivative types, such as NEW VAM, VAM TOP, VAM TOP HC, VAM TOP HT, VAM 21, VAM FJL and other types.
Hunting buckle: Belongs to the Hunting series, and also has different specific models, such as SL HT, SL HC, TH HD, Boss, Apex, SL - Flush, etc.
3. Sealing performance: VAM buckles, especially some airtight buckle type products, usually perform well in airtight performance, and can adapt to the sealing requirements of more complex and harsh oil and gas well environments such as high pressure and high gas content; Hunting buckles also have good sealing performance, but in different working conditions and designs, the airtight effects of the two may be different. For example, in some high-pressure and high-gas ratio natural gas wells, some special designs of VAM may make its gas sealing better, but in other oil and gas wells with relatively low pressure but high corrosion, Hunting buckles may ensure better comprehensive sealing and corrosion resistance through its materials and surface treatment.
4. Connection strength: In terms of connection strength such as tensile strength, compression resistance and torque resistance, the original intention of both designs is to meet the force requirements of oil and gas well pipes during drilling and normal production. However, some models of VAM buckles are widely used in some deep wells, ultra-deep wells and other scenes with extremely high requirements for pipe connection strength and stability; and different models of Hunting buckles may provide stable and reliable connection strength in specific horizontal wells, large displacement wells, etc. due to their unique thread structure and tooth design.
5. Application Scope Focus
VAM buckle: With its diverse models and performance advantages under complex and harsh working conditions, it is widely used in major oil and gas producing areas around the world. For example, it is widely used in offshore oil and gas field development, especially in platform strings for deep-sea oil and gas production. It is also widely used in unconventional oil and gas development such as high-temperature and high-pressure oil and gas reservoirs and shale gas.
Hunting buckle: It is also widely used, especially in some conventional oil and gas field development projects that have balanced requirements for economy and specific performance. For example, in the development of some shallow oil and gas wells on land, some models of Hunting buckle have certain advantages in cost while meeting performance requirements, so it is also used more frequently.
